Biomass co-firing consists of combusting biomass and fossil fuels, mostly coal but also natural gas, in the same power plant. In most cases, biomass co-firing in coal power plants takes place by mixing biomass with coal before the burners, but biomass can also be gasified and burned in separate burners, after which the gaseous fuel or steam is ...
